Abstract
Cloud gaming is increasingly popular. A challenge for cloud providers is to keep datacenter utilization high: a non-trivial task due to the diversity of hardware and applications. We introduce Capsule, a mechanism to seamlessly share datacenter resources across multiple players. We implemented Capsule in the Open 3D Engine (O3DE). Our evaluations show that Capsule increases datacenter resource utilization by accommodating up to 2.25x more players, without degrading user experience. This is the product of Capsule using up to 1.43x less GPU, 3.11x less VRAM, 3.7x less CPU, and 3.87x less RAM compared to the baseline. Capsule is also application-agnostic, i.e., no changes were required to run applications on the Capsule-based O3DE. Our experiences with four applications, three servers with different hardware specifications, including one with four GPUs, and a multi-server cluster shows that the Capsule design can be adopted by other game engines to increase datacenter utilization.
